Two-Way Fluid–Gas Exchange Syringe for Postvitrectomy Patients in Outpatient Setting Pars plana vitrectomy is a surgical procedure for the treatment of diseases such as rhegmatogenous retinal detachment, proliferative diabetic retinopathy, macular hole, and macular pucker (also called epiretinal membrane). In clinical medical practices, complications such as postvitrectomy vitreous hemorrhage, ...

PURPOSE To evaluate the efficacy of repeated pars plana vitrectomy with internal limiting membrane peeling and gas tamponade for persistent macular holes (MHs). METHODS Twenty-nine eyes that underwent repeated pars plana vitrectomy and internal limiting membrane peeling for persistent MHs were included in this retrospective study. Data retrieved included demographic information, visual acuity...

The vitreous sample has been used for the diagnosis of uveitis and intraocular malignancy for decades. The sample volume is usually limited to 1 mL with current techniques. In the present study, a novel technique for higher amount of vitreous sample acquisition, that is, Binocular Indirect Ophthalmo Microscope-assistant gas-perfused pars plana vitrectomy (BAG-PPV) was invented.For diagnostic pu...

Reservoir permeability is a critical parameter for characterization of the hydrocarbon reservoirs. In fact, determination of permeability is a crucial task in reserve estimation, production and development. Traditional methods for permeability prediction are well log and core data analysis which are very expensive and time-consuming. Well log data is an alternative approach for prediction of pe...
